				<td valign="top" class="text"><p>In our previous example, we had combined FusionCharts, 
						ASP.NET and JavaScript to create client side dynamic charts. We were updating 
						the chart by asking it to fetch new data from server and update itself, without 
						incurring any page refreshes.
					</p>
					<p>In this example, <strong>instead of asking the chart to get XML data </strong>from 
						server, <strong>we'll provide updated XML data to chart using JavaScript </strong>
						functions. The chart will simply accept that XML data and render.
					</p>
					<p class="highlightBlock">This method can effectively be used in your AJAX 
						applications, where your JavaScript code gets the updated XML from server and 
						then provides it to charts locally. You can process the data received from AJAX 
						Calls, build XML from it and finally provide it to the chart.
					</p>
					<p><strong>Before you proceed with the contents in this page, we strictly recommend you 
							to please go through the sections &quot;How FusionCharts works?&quot; and 
							&quot;Basic Examples&quot;, as we'll directly use a lot of concepts defined in 
							those sections.</strong></p>

				<td valign="top" class="text"><p>We'll carry on from our previous example 
						and convert it to use JavaScript + XML, so that the new XML is provided to the 
						chart using JavaScript functions - the charts NO more directly request data 
						from server. To attain this, we send all the pertinent data from our server to 
						the end viewer as JavaScript arrays in the same page. The JavaScript arrays are 
						dynamically generated by ASP.NETpages at run-time and filled with data.
					</p>
					<p>Effectively, we will do the following:</p>
					<ol>
						<li>
							Contain both the pie chart (summary) and column chart (detailed) in one page (<span class="codeInline">Default.aspx</span>).</li>
						<li>
							When the page loads, the pie chart would use
							<span class="codeInline">dataXML</span>
							method to show summary of all factories. This data will be built in
							<span class="codeInline">Default.aspx</span>
							itself.
						</li>
						<li>
							There will be a JavaScript array named as
							<span class="codeInline">data</span>
							in this page. This array will contain detailed data for the factories. The 
							array will be dynamically built using ASP.NETand then outputted as JavaScript 
							code.
						</li>
						<li>
							Apart from the data in JavaScript, we'll also have a local JavaScript function
							<span class="codeInline">updateChart()</span>, which would process the data in 
							this array and convert it to XML data document, for direct usage by the column 
							chart.
						</li>
						<li>
							The column chart would initialize with no data, as the user has not selected a 
							factory initially. We'll customize the &quot;<span class="codeInline">No data to display</span>&quot; 
							message of the chart to show a friendly message.</li>
						<li>
							The pie chart would have JavaScript links defined for each pie slice. This 
							JavaScript links refer to
							<span class="codeInline">updateChart()</span>
							JavaScript function present on the same page. We'll later see how to hand code 
							this function. When a pie is clicked, the
							<span class="codeInline">factory ID </span>is passed to this function.
						</li>
						<li>
							The
							<span class="codeInline">  updateChart()</span>
							function is responsible for udapting the column chart. It generates the XML 
							data from data stored in JavaScript
							<span class="codeInline">data</span>
							array and conveys it to the column chart.</li>
						<li>
							The column chart would now accept this XML data, parse it and finally render.</li>
